Application tiled December-l0, 1885. Serial NOISFMQSS. `(No model.)

.To all whom, it may concern:

Be it known that we, G rLnERT MUNDAY and JOHN COON, citizens of the United States of America, residing at Montezuma, inthe county of Mercer and State of Ohio, have invented certain new and useful Improvements in Clod- Crushers; and we do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Our invention relates to certain new and useful improvements in clod-crushers or rotary harrows; and it consistsin the construction and combination of the parts, as will be hereinafter fully set forth, and specifically pointed out in the claims.

In the accompanying drawings,which illustrate our invention, Figurel is a plan view of a clod-crusher or rotary harrow constructedin accordance with my invention; and Fig. 2 is a sectional view of the same, taken through the line x .r of Fig. l.

A refers to the rigid forward frame, which consists of the bars a a and b b. To the forward beam, b, the draft-tongue is attached and thoroughly braced, and immediately in the rear of said draft-tongue is located a central connecting beam, A', above which is located the drivers seat B. To each of the beams a a and to the central beam, A', are attached blocksC,

which are provided at their ends with bear-` This rear frame, D, is attached to the main frame so that it can swing vertically.

The rollers E E are journaled on independent shafts, which have bearings in the blocks C,whicl1 are attached to the beams of the main frame, and the rear cross-beam is provided y with forwardly-projecti ng pins, between which the pins on the rollers E E pass. Immediately in the` rear of the rollers E E are pivotally secured shafts F, each of the said shafts having attached thereto flexible connectionslt, one end of said connections being secured rigidly thereto,while the other end is rigidly attached to the ends of levers H,which are pivotally attached to f rames I, located on' the beams I) I), so that the end portion of the levers will project forwardly within easy reach ofthe driver. The frames I are provided with pcrforations i', through which pass pins for retaining the levers in a fixed position. Y

Each of the rollers or shafts F carry series of teeth a, and by suitably adjusting said levers the teeth can be allowed to assume either a tion. Vhen said teeth are in a vertical position, they serve as barrow-teeth and assist in smoothing the surface of the ground,and when moved to a forwardly-inclined position it will engage with the teeth of the rollers and remove any obstrnctions which may collect upon the same. The rear under sides of the beams b b are recessed, so that the strips or iiexible connections 7L may pass through said recesses.A If desirable, the teeth a may be allowed to assume a rearwardly-inclined position with respect to the rollers E E. Y y,

It will be obvious that when the rear end of each lever H is depressed the tension on the iieXible connection h is relieved, so that-the shaft F is permitted to turn, under the gravity of its teeth, until the latter reach a vertical position. The elevation of the rear end of each lever causes it to draw upon the connection h and partly revolve the Shaft F, to throw its teeth to an inclined position. By removing the pin locking the lever H, and permitting the rear part of the latter to be depressed enables the strap h to give and allow the teeth of the shaft F to drop to a Vertical position, in which position the said teeth and the lever H may be locked by inserting the pin in the opening t, Fig. 2. Of course it will be understood that there may be as many openingsl as may be deemed desirable.

Ve claim* l.. A clod-crusher or rotary barrow, consisting of amain framehaving j onrnaled theretions i, through which pins are adapted to be passed, so as to hold the pivot-bars F in position, substantially as shown, and for the pur- 15 pose set forth.

In testimony whereof we ax our signatures in presence of two Witnesses.
